Edge Categories Distribution

Epistemic Robustness

Epistemic Robustness measures the provenance quality of edges from this knowledge source, using Knowledge Level and Agent Type from the Biolink Model to assess evidence strength and reliability. Higher scores indicate stronger evidence and greater manual curation.

Edge Type Validation

This section shows the validation of edge types in this knowledge source against the recognized biolink schema patterns.

16,136
Recognized Edges
( 58.6 %)

11,381
Unrecognized Edges
( 41.4 %)

ABox / TBox Classification

The TBox-to-ABox balance reflects how much a knowledge graph emphasizes abstract schema versus concrete instances—too much of either can hinder effective learning and reasoning.

1,282
ABox Edges
( 4.7 %)

11,299
TBox Edges
( 41.1 %)
